Exam 3: Protista, Plantae, and Fungi

Protists may superficially resemble organisms in the other kingdoms; one exception is the kingdom _____, whose members do not resemble protists in any meaningful way.

Most of the cells of a multicellular eukaryote are genetically identical yet may become specialized for specific tasks; how can these differences in cell function be explained?

Protists are not considered to represent a complete evolutionary lineage because

Despite some similarities in appearance and habitat selection, biologists consider the fungi more closely related to animals than plants; for example, both groups _____, a feature completely absent in plants.

Fertilization is the event occurring when a(n)

What resources do plants use to produce the sugar molecules that plant cells use for fuel?

Biologists hypothesize several advantages for the larger cell size typically observed in eukaryotes, including

Lichen can be useful as pollution indicator species; lacking a cuticle they tend to readily absorb airborne pollutants.

The defining feature of the angiosperms is the ____________________.

As a major plant group the bryophytes are characterized by

Phytophthora ramorum, the fungus causing sudden oak death, has been spread to uninfected forests on the boots of hikers; what reproductive method is most likely responsible?

Mutualistic organisms are more commonly termed parasites.

In comparison to the above-ground fruiting body, or mushroom, the mass of the underground mycelium is

The flower is the basic reproductive structure of a plant; thus, all plants produce flowers.

In theory, genetic engineers could modify a receptor to allow a plant to recognize almost any biological molecule.

Because healthy forests capture and store large amounts of carbon dioxide as they grow they can moderate the severity of climate change; this type of benefit is termed a(n)____________________.

Although costly to produce, the large number of fruit-producing species attests to its success as an evolutionary adaptation; in what way is fruit production helpful?

Although seeming quite distinct, cotton, morphine, and flour are all obtained from flowering plants, otherwise known as ____________________.

The arrival of a pollen grain on the carpel of a flower or the scale of a female cone is termed

Which protist life strategy is matched with the appropriate nutritional mode?
